posi

I am searching for a 4 bbl intake manifold for my 70 Lark. Does not need to be original. I just want to convert from 2 bbl to 4 bbl. I am also looking for a posi rear end/bolt on rear axle and possibly a set of headers and Quadrajet carb. Thanks in advance for any assistance.....

Can anyone help me identify a rear by the axle tube stamp? I was told it was from a 71 GS, but I'm not positive. The axle tube stamp is LL 00BB. 1006622. It is a posi with an eaton carrier. Any help or information is greatly appreciated...

Anyone experienced with dropping a Buick 455 into a 1955 Century? Turbo400 and a 342 posi? How about 4 link, air bags or disc brakes? Jim Seattle
